  • Actuation of shape-shifting materials has typically required an external trigger. Here, the authors design a shape-memory hydrogel, regulated by a dual network of covalent and temporary hydrogen bonds, whose actuations are encoded by an intrinsic temporal mechanism.

  • Resorbable bioelectronic devices have potential as tools for monitoring physiological parameters, but short functional lifetimes have slowed translation. Here, the authors report succinate-based copolyesters with barrier properties able to extend the functional lifetime of devices.

  • Surface-active macromolecules that are chemically different can be mixed at fluid interfaces if the molecules attract each other, or if they have complementary shapes and a net attraction is induced by a depletant. Now, a strategy that eludes the need for complementarity between the molecules, where tethered molecular brushes induce an entropic net repulsion between like species, achieves long-range arrays of perfectly mixed macromolecules.

  • A polymer code based on a triplet of parameters—network strand length, side-chain length and grafting density—enables materials to be designed with specific combinations of mechanical properties to mimic biological materials.

  • Extracting information about polymer network topology from mechanical properties alone remains challenging. Here the authors develop a forensic approach to quantify network structural information by analysing their nonlinear mechanics.

  • Solvent-free, supersoft and superelastic polymer melts and networks made from bottlebrush macromolecules can display low modulus, high strain at break, and extraordinary elasticity.
